would be uniform, and it is considered that the extreme accuracy of adjustment required for its satisfactory operation would be difficult to secure, particularly wl'iere quantity production and installation desired, and in an apparatus of the above described ch'arac tier, it is desirable for the workrnan to be able to make the installation with the use of com mon tools and without the necessity of drillg g g I i,

the objects of my invention are to provide a construction embodying all the practical advantages of my said prior construction, which is adapted to be produced and furnished forinst-allationin such a form that it may be readily installed, and at the time 01" installation, may be readily and accurately adjusted, so'that, when theclan'iping means is operated, the shield will be firmly clamped at each end to the fixed brackets.

I accomplish these objects by'me'ans of the construction illustrated in the accompanying drawings, in which I I .Fig. 1 is a sectional view at line azw of Fig; 2. i V i 2 is a front'elevati'on, partly broken away, of the complete device embodying my present invention. I

Fig. 3 is an enlarged detail view of one end portion of the device, in longitudinal central section.

Fig. is a front elevation of a: construe-- tion embodying a generic form of my invention.

Fig. 5 is a longitudinal central sectional view thereof.

Figs. 6 and 7 are side elevations thereof showing closed and open positions of the shield. y

In the. drawing, 1 indicates the body, Window casing or other fixed supportingimeans, having a front opening, and"? a wind. shield, or screen adapted and arrangedto' close said opening,' said shield being adj ustably mounted on the body'to swing about a pivot?) at each, enchand at its upper edge, from a near ly vertical position, in 'wl'iich the opening willbe fullyelosed therebyand forwardly to various more or less'open' positions.

i-Xfccoi'dingto'niy present invention I rovideapair of bracketsl, which are rigidly fined in vertical positions on the body, or casing, about the shield opening, one bracket being arrangedat each end oftlleopening, and said brackets being preferablyformed of stiff sheet metal, having slight resiliency, and being sectired to the body at one edge in any suitable manner, as by cars l. Said brackets are arranged to project rearward from the casing i i planes perpendicular to the axis about wl'i' ch the shield 2 swings, and each bracket has an are shaped slot 5 formed therein, the edges of which ai e concentric with the axis oi the shield,oppositely disposed clamping faces being provided at each side of the slots. c

pair'of metal ar'msG are fiired on the shield at each end thereof, at a short distance below its pivotal supports and closely adjacent inner,*or adjacent sides of the brackets 4, respectively, said arms extending, whenthe shield is in' closed position, rearwardly and then-npivardly in an oblique direction to points adjacent the upper ends of the brackets it. The arms 6" are each provided with ascrew threaded aperture in the end portions thereof, saidapertures being arranged inren'tral alignn'rent and in such agpositi on that their line of centers intersects an are which is concentric with, and midway between sidesot' the slots 5 of the brackets, as indicated in Fig. 1. The afperture, i1r th'e arm 6 at the right end of the shield isprovided with aloft thread and, .7

thread, and a? straight tube 7 is provided, which has correspondingexternal rightand left threads at its ends,wl'1fich are respectively screwed into the correspondingarms' 6, so

that in the arm at the left with a right that, when thethbe is rotated in one direction, the arms 6will be sprung, away from eaclrothei' and wlie n itis reamed in the opposite direction they will be "sprungtoward s eaclrother. A handle 8 isinoinited on the tube at any convenient intermediate point and fii 'n'lgv' secured thereto, as indicated. it rod 9 is "extended thru thejtube 7 and beyond the ends thereof, the end portions of therod" being: respectively located infth slots 5 of the adjacent brackets and being extending beyond .the opposite or outer sides of the brackets to a sufficient extent to receive nuts 10, which are threaded thereon.

When installing the device, the nuts are screwed onto the end portions of the rod until the faces of the nuts are held in close proximity to the adjacent faces or sides of the brackets, but normally do not positively engage the same. The sides of the arms about the apertures therein, and next to the adjacent brackets, form clamping faces, which are adapted to be engaged with the adjacent faces of the brackets at each side of the slots tl'iercin. Under normal. conditions the faces on the arms are also disengaged from the brackets. as indicated in the full line position of Fig. 3. Under these conditions the shield may be readily swung on its pivots, or adjusted to any position to which it is adapted for adjustment, the rod 9 being moved in the slots 5, as the shield is swung. I

.Vhen it is desired to lock the shield in any position to which it may have been adj usted, the tube 7, by means of the handle 8, is turned to the right, sothat both end portions thereof are unscrewed from the arms 6 in which they are threaded, and, as a result, the end portions of the arms are sprung towards the brackets adjacent thereto until they engage the same and then, on further rotation of the tube, the brackets will be sprung apart until their outer sides engage the faces of the nuts 10, as indicated in the dotted line position of Fig. 3, and, when the tube has been turned to the right as far as possible, each bracket will be firmly clamped between the nut and arm at each side thereof, so that each arm will thus be firmly locked to its adjacent bracket, locking the shield in its adjusted position. To unlock the shield so that it may be adjusted, it is merely necessary to turn the tube 7 to the left, so as to permit the arms to spring away from the brackets and the brackets to spring away from the nuts 10. It is to be noted in this connection that, as the nuts are connected by the rod 9, which is adapted to slide longitudinally in the tube 8, the clamping action cannot take place at one end of the shield without taking place at the opposite end, and that both arms are clamped simultaneously to the brackets witlrequa-l force. Also, that, after the nuts 10 have been adjusted on the rod, so that the distance between their face ends is onlyslightly greater than the distance between the opposite faces of the brackets, further adjustment thereof is unnecessary, and the nuts may be locked in position on the rod by upsetting the ends of the rod, or in' any other suitable manner, and become fixed abutments on the rod.

This arrangement is advantageous as it enables the device to be attached and adjusted readily to different conditions, due to slight variations in the relative positions in which the arms are attached to the shield and the brackets to the casing, the tube being adjustable in the arms and the nuts being likewise adjustable on the rod, to a sufficient extent to provide'for all usual conditions, it being understood that the lengths of the rod and tube will be adapted to the particular construction to which the device is to be applied. The parts may then be adjusted so that they may be moved between a locked and an unlocked position by a very slight portion of a turn of the tube, and the clamping action on each bracket will always be the same. That is, the adjustment may be such that in the unlocked position, the adjacent faces of the arms and brackets may be in sliding contact, provided the frictional engagement therebetween is insuflicient to interfere with the ready adjustment of the wind shield. The advantages, so far as the facility of adjustment and of locking and unlocking, by means of a single handle, are concerned, are the same as with my said prior construction.

A modified form of my generic inven tion' may be employed in connection with a single bracket and locking means located at the middle of the shield, where the ad vantages of a look at both ends of the shield are not desired, as shown in Figs. 4: to 7.

In this form, 1 preferably provide a pair of parallel arms 11 and 12, which are formed integrally with a base 13, the latter being attached to the middle upper portion of the frame 1 in which the glass of the shield 2 is mounted, and a bracket 15 is mounted on the casing close to the oppositeside of the arm 11 from arm 12, said bracket 15 being similar in all respects to the brackets 4 previously described and being provided with an are shaped slot 16 having as its center the axes of the shield frame 13, which is mounted on pivots 22. The arms 11, 12 have aligned apertures in their ends, which also'align with the slot 15, and a tube 17 is provided which is threaded into the aperture of the arm 11 at one endand abuts at its opposite with the adjacent side of the arm 12. A bolt 18, having a head 19, is passed thru the arm 12, tube 17 and slot 16 and a nut 20 is threaded on the opposite cnd of the bolt and screwed thereon to such a point that the head 19 willbe engaged with the adjacent side of the arm 12 when the face of the nut is in close proximity to the side of bracket 15. A handle 21 is mounted on the tube 17 and rigidly secured thereto. When the frame is adjusted on its pivots 16 the bolt 18 moves in the slot 16 as indicated in Figs. 6 and 7. j

With this construction the locking action is similar to that in the construction first described. As the tube 1? abuts against the c axis, and I said arm I of the arm,
